PGM1 and TF subtypes and C3 polymorphisms in Continental Italy and Sardinia. Data on the world distribution of these genetic markers

PGM1, TF and C3 polymorphisms have been examined in two Italian samples, collected in continental Italy and in Sardinia (Cagliari). The PGM1 and TF subtypes were determined by isoelectric focusing while the C3 was studied by conventional methods. A significant difference in the gene frequencies of PGM1 and TF systems between our two samples has been observed. In addition, data on the world distribution of PGM1, TF and C3 polymorphisms have been presented.
